2012 4dr Hatch 155-horsepower 2.0L I4
6-speed shiftable automatic FWD
I drive it on the highway at a constant speed of about 78 with the cruise control on, for my daily commute . Very little traffic on my commute, and speed limit is 70. I get about 33 mpg, or 380 miles per tank. I've found that long-range runs of an hour or more seems to burn out the gunk, and I have better fuel economy for the next week or two. I figure driving near 80 is killing the advertised 39 mpg with the Skyactiv engine. see full Mazda Mazda3 review

Hard to beat 40 mpg in a car that drives as well and has the performance of the Mazda3. Most ZOOM ZOOM for the price of any car I test drove. see full Mazda Mazda3 review

This car does very well.. I drive mostly highway during the week, but a lot of rush hour driving means lots of stop and go. Even with that and the around town driving I do on the weekends, I am still averaging 38.1 MPG! see full Mazda Mazda3 review

While reviews are mixed, the Skyactiv engine delivers as promised for me. With over 70% city/suburb driving, I've yet to average under 30mpg (odo/pump). Set the cruise control at 65-70 and > 40mpg is easy on a flat highway. see full Mazda Mazda3 review

2013 4dr Hatch 155-horsepower 2.0L I4
6-speed shiftable automatic FWD
Fuel economy has been OK. I usually do a 50/50 mix and in good weather, I get in the high 7s/100km or about 30 MPG. In the cold weather, it's been closer to 9L/100km or about 26 MPG. Strangely, it's about the same economy I got with my 99 Civic w/ 4 spd auto. see full Mazda Mazda3 review

I have the Grand Touring model with the upped engine. Fuel economy is very poor compared to other cars in its class. see full Mazda Mazda3 review

22 mpg (city) in a car this small is abysmal. 27 highway is worse. see full Mazda Mazda3 review
